Question

Look at the figure below.
What is the value of x?

Answer 1

The is no figure below, therefore \(x = \textbf{undefined}\)

Answer 2

These are similar triangles.

\( \color{Black}{\Rightarrow 6:13 = x+9:14 }\)

Can yew solve it?

Answer 3

\( \color{Black}{\Rightarrow 13x + 117 = 84 }\)
Solve now?

Answer 4

never mind that is wrong, i forgot about the =84 part..let me solve again

Answer 5

I got -2.53..is that right?

Answer 6

6:13 :: x+9:14+(x+9)

Answer 7

6(14+(x+9)) =13(x+9)
Try that and see if you obtain one of the answer options.

Answer 8

84+6x+54 = 13x + 117

Answer 9

-7x= -21
x=3

Answer 10

@hellokitty357, I dont think -2.53 is correct. For one thing it is not going to be a negative value.
